The Picasso Spatula is an essential item for base makeup. Although many brands have released spatula products, the collaboration between Picasso and makeup artist Ham Kyung-sik is the original. It helps create a thin and smooth base, so I always use it during my base makeup routine. I also find myself using it effectively when applying moisturizer or primer, even if I'm not using foundation. Because it allows for multiple thin layers, it enables a thin, non-thick base finish.
